Theorem 3.2 ([1]}) 
Let \(\mathcal {H}: \mathbb {R}^n \rightarrow [-R, R] \) , \(\mathcal {F}_{L,a}: [-R, R] \rightarrow \mathbb {R}\)  are \(L\) -Lipschitz functions and \(f(0) = a\)  for some fixed \(a\) . Denote \(\mathcal {F}_{L,a} \circ \mathcal {H}:=\lbrace f(h(\cdot )):f\in \mathcal {F}_{L,a},h\in \mathcal {H}\rbrace \) . The Rademacher complexity satisfies
\(\hat{\mathcal {R}}_m*{ \mathcal {F}_{L,a} \circ \mathcal {H}} & \le cL*{ \frac{R}{\sqrt{m}} + \log ^{3/2}(m)\hat{\mathcal {R}}_m(\mathcal {H}) },\)
